Sahih Muslim , Book 42, Hadith 7098 (USC-MSA) ⓘ

Abu Hazim reported: I saw Abu Huraira point with his finger many a time and saying: By One in Whose Hand is the life of Abu Huraira, Allah's Apostle could not eat to his fill and provide his family bread of wheat beyond three days successively until he left the world.

حَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ يَزِيدَ بْنِ كَيْسَانَ، حَدَّثَنِي أَبُو حَازِمٍ قَالَ رَأَيْتُ أَبَا هُرَيْرَةَ يُشِيرُ بِإِصْبَعِهِ مِرَارًا يَقُولُ وَالَّذِي نَفْسُ أَبِي هُرَيْرَةَ بِيَدِهِ مَا شَبِعَ نَبِيُّ اللَّهِ صلى الله عليه وسلم وَأَهْلُهُ ثَلاَثَةَ أَيَّامٍ تِبَاعًا مِنْ خُبْزِ حِنْطَةٍ حَتَّى فَارَقَ الدُّنْيَا ‏.‏
